A have a ballerina figurine with a blue "N" on the bottom .... who made it?
Your ballerina looks similar to Nao Lladro figurines I just can figure out what particular one it is since there is no mention of any year from your end. Anyways most of those kind of figurines sell for $100 or lesser unless it is a rare kind.
I added a picture of the cobalt blue N marking on the bottom of the figurine .... was this ever used to identify Nao Lladro figurines?
That's not a figurine from Nao Lladro. The trademark is no the same. the N on your figurine looks as though it was written with a pen. However, I haven't seen any manufacturer that caries that trademark yet. Capo di Monte's N always carries a crown. Without the "n", it looks like a Staffordshire figurine. But from where I am sitting, I can't possibly tell. Also, it's possible it was made specially for a certain Aristocrat family, back in the days. I will advise that you take that piece to an antique store and get it appraised when you have the time. Best of luck
